Q8. Look at the image.
Answer:
Option B
Step-by-step explanation:
Quadratic equation given in the question is,
[tex]x^2+4x+2=0[/tex]
By comparing this equation with the standard quadratic equation,
[tex]ax^2+bx+x=0[/tex]
[tex]a=1,b=4[/tex] and [tex]c=2[/tex]
By using quadratic formula to get the roots of the given quadratic equation,
[tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
By substituting the values of a, b and c in the formula,
[tex]x=\frac{-4\pm\sqrt{4^2-4(1)(2)}}{2(1)}[/tex]
[tex]x=\frac{-4\pm\sqrt{16-8}}{2}[/tex]
[tex]x=\frac{-4\pm\sqrt{8}}{2}[/tex]
[tex]x=\frac{-4-\sqrt{8}}{2},\frac{-4+\sqrt{8}}{2}[/tex]
[tex]x=-3.414,-0.5857[/tex]
[tex]x=-3.41,-0.59[/tex]
Therefore, Option B will be the answer.

Write the equation of the line Perpendicular to g (x) = 3x – 0.77, going through the point (0,-5). Show all work.
Answer:
y = -⅓x - 5
Step-by-step explanation:
the slope of g(x) = 3
=> the slope of the line perpendicular
to g(x) = -1 /3
so,
the line is :
y +5 = -⅓(x-0)
y = -⅓x - 5
On comparison to slope intercept form
slope=m=3Perpendicular lines have slopes negative reciprocal to each other
Slope of perpendicular line=-1/3

A restaurant offers three types of meats: chicken, beef,
and pork. The waiters surveyed 50 customers at random
about their favorite type of meat. The results are listed in
the table and on the graph below. If the restaurant
orders 400 pieces of meat, how many pieces should be
chicken?
Answer:
200
Step-by-step explanation:
If the waiters surveyed 50 customers and half of the customer's favorite meat was chicken, then if 400 pieces of meat were ordered 200 pieces should be chicken.
If [tex]\frac{50}{chicken}[/tex] = [tex]\frac{50}{25}[/tex] = [tex]\frac{1}{2}[/tex], then [tex]\frac{400}{chicken}[/tex] = [tex]\frac{400}{2}[/tex] = [tex]2[/tex]

Find the distance between the two points.

Enter the number that

radical symbol.
Answer: 89 will go in the box
This means the exact distance between the two given points is [tex]\sqrt{89}[/tex] which approximates to roughly 9.4339811
===========================================================
Explanation:
To get that answer, we can apply the distance formula
(x1,y1) = (-1,-5) is the first point
(x2,y2) = (4,3) is the second point
Plug the coordinates into the distance formula
[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(-1-4)^2 + (-5-3)^2}\\\\d = \sqrt{(-5)^2 + (-8)^2}\\\\d = \sqrt{25 + 64}\\\\d = \sqrt{89}\\\\d \approx 9.4339811\\\\[/tex]
--------------------------
Alternative Method:
You could also form a right triangle by adding the point (4, -5). The horizontal leg goes from (-1,-5) to (4,-5) which is a span of 5 units. The vertical leg goes from (4,-5) to (4,3) which is a span of 8 units. The hypotenuse is from (-1,-5) to (4,3) which is the distance we want to find.
After forming the triangle and determining the leg lengths, use the pythagorean theorem and you should get [tex]\sqrt{89}[/tex] as the length of the hypotenuse. As you can probably guess, the distance formula is effectively a slight rephrasing the pythagorean theorem.
Departmental Store Agora claims that their mean weekly sales of Aerosol were at most 2,400 packages over the past 6 months and population distribution is unknown. The manager wants to check if the sales have decreased in recent times. He obtained a random obtained sample of sales data from 61 stores and found that the sample mean is 3,593 packages with sample standard deviation 4919. At 7% significance level, using critical value approach see if the claim is true or not.
Answer:
There is enough statistical evidence to suggest that the department's claim is not true
Step-by-step explanation:
The mean weekly sales μ₀ ≤ 2,400 packages
The period over which the weekly sales were measured = Over the last 6 months
The number of stores in the sample, n = 61 stores
The sample mean, [tex]\overline x[/tex] = 3,593
The sample standard deviation, s = 4919
The significance level = 7% = 0.07
The critical value approach
The null hypothesis, H₀; μ ≤ μ₀
The alternative hypothesis, Hₐ; μ > μ₀
The test statistic is given as follows;
[tex]t=\dfrac{\bar{x}-\mu }{\dfrac{s}{\sqrt{n}}}[/tex]
We get;
[tex]t=\dfrac{3,593-2,400}{\dfrac{4,919}{\sqrt{61}}} \approx 1.894[/tex]
With df = n - 1 = 61 - 1 = 60 at 7% significant level, from a graphing calculator the critical-t, = 1.495598
The p-value at the test statistic is between 0.01 and 0.005
Given that the p-value is less than the significant level, and the test statistic is larger than the critical-t we reject the null hypothesis, that the mean weekly aerosol sale is less than 2,400 packages.
Therefore, there is sufficient statistical evidence to suggest that the departments claim is not true and the mean sales of Aerosols have increased to more than 2,400 packages

Find the volume of a pyramid with a square base, where the perimeter of the base is 10.7\text{ ft}10.7 ft and the height of the pyramid is 9.8\text{ ft}9.8 ft.
The volume of the pyramid is 23.375 ft^3.
We have,
Volume = (1/3) * Base Area * Height
In this case, the base of the pyramid is a square, and the perimeter of the base is given as 10.7 ft.
The perimeter of a square is equal to 4 times the length of one side.
Let's denote the length of one side of the square base as s.
And,
4s = 10.7
Solving for s:
s = 10.7 / 4 = 2.675 ft
Base Area = s^2
Plugging in the value of s:
Base Area = (2.675 ft)^2 = 7.156 ft^2
Now,
Volume = (1/3) * Base Area * Height
Volume = (1/3) * 7.156 ft^2 * 9.8 ft
Volume = 23.375ft^3 (rounded to six decimal places)
Therefore,
The volume of the pyramid is 23.375 ft^3.

2 out of 50 are defective.
Divide 2 by 50: 2/50 = 0.04
Now multiply the total quantity by that:

In the above figure, m∠P = 125° and m∠Q = (5x)°. If angles P and Q are supplementary angles, what are the value of x and the measure of angle Q?
Answer:
I had the same question and the answer is x = 11, m∠Q = 55°
The value of x is 11 and measure of <Q is 55 degree.
What are supplementary angle?Angles that add up to 180 degrees are referred to as supplementary angles. For instance, angle 130° and angle 50° are complementary angles since the sum of these two angles is 180°.
We have,
m∠P = 125° and m∠Q = (5x)°.
and, P and Q are supplementary angles.
Using the property of Supplementary Angle
<P + <Q = 180
125 + 5x= 180
5x = 55
x= 11
Thus, the measure of <Q
= 5x
= 55 degree

Answer:
The area of the composite area is 400 square millimeters.
Step-by-step explanation:
The area of the composite figure ([tex]A[/tex]), in square millimeters, is found by multiplying the area of the equivalent rectangle, in which a semicircle of the original rectangle is move to the opposite side of the figure, so that quantity of area is conserved:
[tex]A = w\cdot h[/tex] (1)
Where:
[tex]w[/tex] - Width, in millimeters.
[tex]h[/tex] - Height, in millimeters.
If we know that [tex]h = w = 20\,mm[/tex], the area of the composite figure is:
[tex]A = (20\,mm)\cdot (20\,mm)[/tex]
[tex]A = 400\,mm^{2}[/tex]
The area of the composite area is 400 square millimeters.
